public function ForwardFormFormatter::prepareView in Forward 4.x

Same name and namespace in other branches

1. 4.0.x src/Plugin/Field/FieldFormatter/ForwardFormFormatter.php \Drupal\forward\Plugin\Field\FieldFormatter\ForwardFormFormatter::prepareView()

Allows formatters to load information for field values being displayed.

This should be used when a formatter needs to load additional information from the database in order to render a field, for example a reference field that displays properties of the referenced entities such as name or type.

This method operates on multiple entities. The $entities_items parameter is an array keyed by entity ID. For performance reasons, information for all involved entities should be loaded in a single query where possible.

Changes or additions to field values are done by directly altering the items.

Parameters

\Drupal\Core\Field\FieldItemListInterface[] $entities_items: An array with the field values from the multiple entities being rendered.

Overrides FormatterBase::prepareView

public function prepareView(array $entities_items) {
  foreach ($entities_items as $item) {

    // If the display field is empty, it means the edit widget
    // has never been used for this entity. In this case,
    // default to display the link.  The user can then edit
    // the entity and hide the link if needed.
    if ($item
      ->isEmpty()) {
      $display = TRUE;
      $item
        ->appendItem($display);
